An infusion pump system includes a removable in vivo glucose sensor for monitoring glucose concentration level in a patient, and for signaling an infusion pump to deliver a selected medication such as insulin to a patient. The glucose sensor comprises a sensor cable for placement through a catheter to position a distal sensor tip at a selected in vivo sensor site. A proximal end of the sensor cable seats within a connector fitting mounted on the catheter at a convenient and accessible subcutaneous position. The connector fitting couples the sensor cable to an implanted control unit which signals the infusion pump to deliver the patient medication. In a preferred system, the infusion pump is also implanted and receives control signals via a direct or telemetric connection. The sensor cable is easily accessed at the connector fitting for periodic sensor removal and replacement, without requiring removal or replacement of other system components.
A system for delivering medication to a patient, comprising: a sensor unit including implantable glucose sensor means for in vivo monitoring of a patient blood glucose parameter, an implantable connector fitting for supporting said sensor means within a patient to permit transcutaneous access to sai
A system for delivering medication to a patient, comprising: a sensor unit including implantable glucose sensor means for in vivo monitoring of a patient blood glucose parameter, an implantable connector fitting for supporting said sensor means within a patient to permit transcutaneous access to said sensor means for removal and replacement without removing said connector fitting from the patient, and control means coupled by said fitting to said sensor means for generating a signal representative of the monitored patient parameter; and pump means for administering medication stored therein to the patient, said pump means including means responsive to said signal to administer the medication in accordance with the monitored patient parameter; said sensor unit further comprising a catheter having one end connected to said connector fitting and adapted to extend from said fitting generally to a selected in vivo sensing site within the patient, said sensor means comprising a sensor tip and cable means having a distal end thereof connected to said sensor tip and a proximal end for removable mounting within said connector fitting, said cable means extending from said fitting through said catheter.
